Hereinafter, a preferred embodiment of the present invention will be described in detail according to the accompanying drawings.

The present invention detects the user's walking information through a pressure sensor, induces the user's desirable walking habits unconsciously through the vibration sensor, and recognizes the blood flow information flowing on the soles of the feet, so that normal blood circulation and vascular disease It is intended to provide an insole system equipped with an Internet of Things function capable of detecting an abnormal symptom for in advance, and the present invention provides an insole body 100 and a wireless communication module 200 as shown in FIGS. 1 and 2. And a smart terminal 300.

Hereinafter, for convenience of explanation, all people who use the present invention are referred to as'users', and the direction in which gravity acts is referred to as'top', and the direction opposite to gravity is referred to as'bottom'. This will be explained.

The insole body 100 is formed to have a shape corresponding to the inner floor of the user's shoe, and absorbs a shock when walking and obtains pedestrian tax information at the same time.

As shown in FIG. 1, the insole body 100 includes a first insole member 110 formed of a shock absorbing material to protect the sensor on a surface corresponding to the inner bottom of the shoe, and the first insole member 110 And a second insole member 130 formed in a shape corresponding to the first insole member 110 while covering the sensor unit 120 and the sensor unit 120 attached to the upper end of the sensor unit 120.

In addition, the sensor unit 120 transmits vibration to induce walking in a correct posture in contrast to the pressure sensor 122 for detecting the user's walking pressure line, and the normal pressure center line L and the user's walking pressure line. It includes a vibration sensor 124 for.

Here, the pressure sensor 122 detects a plurality of walking information including the walking speed of the user and the walking pressure line of the user compared to the normal pressure center line L, and the detected walking information is in the insole body 100 It is transmitted to the smart terminal 300 through the attached wireless communication module 200.

Hereinafter, it will be described in more detail according to an embodiment of the sensor unit 120 according to the present invention.

The sensor unit 120 according to the present invention includes a first base member 121 of a predetermined size having a shape of a shoe insole as shown in FIG. 2, and the first base member 121 at a predetermined interval. A plurality of pressure sensors 122, a second base member 123 having a size corresponding to the first base member 121, and a plurality of vibration sensors installed at predetermined intervals on the second base member 123 Includes 124.

Here, the plurality of pressure sensors 122 are uniformly arranged with an interval of 5 to 10 mm over the entire area of the first base member 121 to accurately detect the user's gait.

Here, if the distance between the pressure sensors 122 is less than 5 mm, the distance between the pressure sensors 122 is narrow, so it is difficult to fix the pressure sensor 122 to the first base member 121, which is not preferable, and the pressure sensor 122 If the distance of) exceeds 10 mm, the distance between the pressure sensors 122 is wide and it is difficult to accurately detect the detected walking pressure line, which is not preferable.

In addition, the pressure sensor 122 is arranged at a distance (W) of approximately 10 to 12 mm from both edges of the first base member 121, which is the edge of both sides of the first base member 121 when the user is walking. It is due to the fact that there is no great difficulty in accurately detecting the walking pressure line even if the pressure sensor 122 is not disposed in the corresponding part because there are not many cases of walking so that the weight is biased toward the side.

And the first base member 121 is divided into a bottom layer (no drawing symbol) and a surface layer (no drawing symbol), and the pressure sensor 122 is interposed between the bottom layer and the surface layer, and then the bottom layer and the surface layer are integrally molded with each other. This allows the position of the pressure sensor 122 to be firmly fixed.

At this time, a surface layer is formed with a thickness (T) of 2 to 5 mm on the upper surface of the pressure sensor 122, which is easily torn between use when the surface layer thickness (T) is less than 2 mm. ) Is not desirable because it may be out of position, and if the thickness (T) of the surface layer is formed thicker than 5 mm, the pressure sensing performance may be deteriorated due to the thick surface layer when pressure is sensed through the pressure sensor 122 It is not desirable.

Through the pressure sensor 122 as described above, the pressure applied to the insole body 100 during walking is sensed for each position where the sole of the foot is in contact, and through this, the walking pressure line connecting the heel and the heel during walking is real-time. Will be detected.

In addition, various walking information such as the number of steps and walking speed of the user may be estimated by using the walking pressure detected through the pressure sensor 122. For example, after the walking pressure is detected at the heel of the foot, When the walking pressure is sensed from the side, it can be seen that the foot has been stepped a predetermined distance toward the front of the user and then became a supported foot through walking, and in this case, it is assumed that the foot has walked once.

Through this, the number of steps is estimated by determining the number of times the walking pressure is detected once the walking pressure connecting the heel and the heel is detected, and the time difference in which the walking pressure connecting the heel and the heel is repeated is calculated. Walking speed is estimated.

In addition, the user's walking pressure line detected in real time through the pressure sensor 122 is compared with the normal pressure center line L preset through the application of the smart terminal 300 through the wireless communication module 200, Through the vibration sensor 124 so that the user's walking pressure line follows the normal pressure center line (L), the walking posture is corrected.

For this, the vibration sensor 124 is arranged to be located at the same position as the position where the plurality of pressure sensors 122 are arranged on the second base member 123 as shown in FIG. When walking in an undesirable posture away from the line (L), based on the pressure input at the wrong position, the vibration of an appropriate intensity is generated from the vibration sensor 124 at a position corresponding to the position of the pressure sensor 122. Control, and through this, it is possible to correct the user's wrong gait by being conscious of it through vibration.

At this time, the vibration sensor 124 is installed in a form in which the upper surface is exposed from the upper surface of the second base member 123 or protrudes at a predetermined height, through which vibration generated by the vibration sensor 124 is a second insole member ( 130).

On the other hand, the walking pressure line sensed through the pressure sensor 122 is compared with the normal pressure center line (L) set in advance through the smart terminal 300 to be described later, and the walking pressure line is the normal pressure center line (L). In the case of deviating from, the vibration sensor 122 at the deviated position is controlled through the smart terminal 300 to generate vibration.

Above, only allowing the user to correct the gait by the vibration generated through the vibration sensor 124 has been described, but in addition to this, while the user adjusts the intensity of the vibration generated through the vibration sensor 124, It can be used to check the intensity of vibration and to determine how much the nerves (sensations) of the soles are damaged.

The second insole member 130 is located on the upper end of the sensor unit 120, that is, on a surface corresponding to the user's sole, and is formed of a shock absorbing material to protect the sensor and reduce fatigue applied to the user's sole.

A blood flow sensor 131 in the form of a thin film for measuring blood flow information including the user's blood flow rate is provided inside the second insole member 130, and the user is The blood flow information of the sole of the foot is measured.

The blood flow information measured through the blood flow sensor 131 as described above is transmitted to the smart terminal 300 through the wireless communication module 200 to be described later, whereby the user can easily use a plurality of methods such as pictures, texts, and graphs. It is visualized and displayed on the screen for confirmation.

The wireless communication module 200 is installed in the insole body 100 and transmits pressure information detected through the pressure sensor 122 of the sensor unit 120 to the smart terminal 300 to be described later, and The control signal is transmitted to the vibration sensor 124 of the sensor unit 120 and the blood flow information detected through the blood flow sensor 131 of the second lead member 130 is transmitted to the smart terminal 300.

The wireless communication module 200 is composed of any one module selected from Bluetooth or Zigbee, which is widely used for short-range wireless communication.

In addition, the wireless communication module 200 is installed between the first and second insole members 110 and 130, through which the impact caused by weight or external force is not transmitted to the wireless communication module 200 as it is, so that it is not easily damaged. do.

The smart terminal 300 receives walking pressure information sensed through the pressure sensor 122 of the sensor unit 120, compares it with the normal pressure center line L, and controls the operation of the vibration sensor 124 through this. , It is a configuration that visually outputs the user's walking information and blood flow information through a screen.

The smart terminal 300 is selected from smart devices such as a smart phone and a tablet PC, and the smart terminal 300 receives information sensed from the insole body 100 and makes it visible. An application for outputting to is installed.

Hereinafter, an embodiment of an application installed in the smart terminal 300 will be described.

The application installed in the smart terminal 300 is when walking information and blood flow information are detected and transmitted from the pressure sensor 122 and the blood flow sensor 131 of the insole body 100, the walking information transmitted to the smart terminal 300 ( Walking speed, number of steps, pedestrian tax, etc.) and blood flow information are quantitatively or qualitatively converted, and the converted walking information and blood flow information are visualized as text, pictures, and graphs as shown in FIG. As a result, the user can visually check the walking information and blood flow information.

To this end, the application includes a walking information output unit 310, a blood flow information output unit 320, and a vibration intensity control unit 330, as shown in FIG. 5.

Here, the walking information output unit 310 is configured to indicate the user's walking speed, the number of steps, and the pedestrian tax. In this walking information output unit 310, the walking speed is output through a graph in real time, and the number of steps is counted as a number. It is configured to be output, and the gait is divided into good, normal and bad, and output.

In addition, a picture in the shape of an insole body is output to the walking information output unit 310, and the normal pressure center line (L) and the walking pressure line are merged and output to the picture so that the user's gait is easily compared in real time. .

At this time, in addition to the normal pressure center line (L) and the walking pressure line, the part where the wrong pressure is applied is colored in red, and the part where the normal pressure is acting is colored in blue, so it is easy to check the wrong gait with just the contrast of the color. It can be configured to be.

Meanwhile, a picture of a shape corresponding to the shape of the sole of the foot is output to the blood flow information output unit 320, and the blood flow information sensed through the blood flow sensor 131 is displayed as color information such as red, yellow, green, and blue. Will be printed.

Here, the red color is the part where the temperature higher than the upper limit allowable temperature is detected based on the normal temperature, the yellow and green color is the part where the low temperature and the high temperature are detected among the temperatures between the normal temperature and the upper and lower limit allowable temperatures, and the blue color is This is the part where a temperature lower than the lower limit allowable temperature is detected based on the normal temperature.

In addition, the vibration intensity control unit 330 is configured to adjust the vibration intensity of the vibration sensor 124, and through this, when the intensity of the vibration felt by the user is strong or weak, the vibration intensity can be appropriately adjusted.

Meanwhile, the smart terminal 300 further includes an initial setting unit 340 for automatically setting the normal pressure center line L through body information such as a user's foot size and weight.

At this time, the initial setting unit 340 operates according to the instruction output through the smart terminal 300 by wearing the shoe into which the insole body 100 is inserted, instead of directly inputting body information such as foot size and weight. It may be configured to automatically input necessary body information.

In this example, the user is guided to walk 5 to 10 steps while wearing shoes, and through this, information on the average stride length of the user is obtained.

In addition, the toe and heel positions are estimated based on the pressure information repeatedly inputted while walking, and the user's foot size is estimated based on this.

In addition, the user's weight is estimated through a change in pressure sensed through the plurality of pressure sensors 122.

In addition, the user's leg length is estimated using the obtained stride length information and the average stride angle (15-20°) during walking in general. Here, if the length of the user's legs is the same and the angle of the ground and both legs are the same when walking, the length of the legs can be obtained by knowing the stride width and the stride angle.

Above has been described as estimating the user's leg length by applying the average stride angle during walking, but unlike this, a gyro sensor (not shown) is installed on the heel side of the insole body 100, and when walking through the gyro sensor By measuring the angle at which the heel is lifted, the user's stride angle is measured, and through this, the user's leg length is estimated.

As described above, instead of separately inputting body information by the user, the body information required to set the normal pressure center line (L) can be automatically acquired through the user's walking motion, through which the user inputs incorrect body information. This prevents the false normal pressure center line L from being set.

As described above, in the present invention, since the user's walking pressure line can be recognized compared to the normal pressure center line, and vibration can be felt through the vibration sensor, walking in a correct posture can be induced, and it is preferable to ground the heel to the toe on the ground. The line indicating the normal walking method, that is, the normal pressure center line, is set, and the walking pressure line indicating the line that the sole of the foot contacts when the user is actually walking is sensed through the pressure sensor. When the walking pressure line is prepared, the vibration sensor installed in the separated part is operated, so that the user can recognize the desired pedestrian position by himself through vibration and correct it to be the correct pedestrian position.

In the above, for the convenience of explanation, the drawings showing the preferred embodiments and the configurations shown in the drawings have been described with reference numerals and names, but this is an embodiment according to the present invention and is It is limited and the scope of the rights should not be interpreted, and the simple substitution with a configuration that has the same effect as a change to a variety of predictable shapes from the description of the invention is within the range that can be changed for easy implementation by a skilled person. You will see it extremely self-evident.
